He's talking about using a three π or four π speaker minus tweeter as a bass bin. The three π uses the Delta 12LFA and the four π uses an Omega 15 or JBL 2226. Plans are also available for a couple of dedicated subs that aren't listed on the website. There is a three π sub, which uses a LAB12 and a four π sub, which uses a JBL 2245.
